STATIONARY WASH-STAN D.

SPECIFICATION forming part of Letters Patent No. 250,626, dated December6, 1881.

Application filed September 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, J AMES BIROKHEAD, J r., of the city of Baltimore,and State of Maryland, have invented certain Improvements in StationaryWash-Stands, of which the following is a specification.

The object ofthis in vention is to prevent the escape of deleteriousgases from the wastepipe and overflow-channel of a stationary washstand;and it consist in combining with the bowl and top of the wash-stand acover having a rigid center piece of considerably less diameter than theinterior of the bowl, and a rim of sheet rubber which exceeds thediameter of the bowl sufficiently to cause the cover to be dished orflared, so as to produce a tight joint when the same is inserted in thebowl.

In the further description of my said invention which follows, referenceis made to the accompanying drawings, forming a part hereof, and inwhich Figure I is a sectional view of a stationary wash-stand providedwith my improvements. Figs. II and Ill are views of the cover on anenlarged scale.

Similar letters of reference indicate similar parts in all the views.

A is thetop of the wash-stand, andB the bowl secured underneath thesame. The diameter of the opening in the top A is less than that of theupper end of the bow], consequently an overhanging annular lip is formedwith which the edge of the cover comes in contact to form a tight joint,as will be hereinafter more fully described.

0 is the cover, which consists oftwo, preferably metallic, plates, toand b, secured together, one of which, a, is offset at its edge to formwith the other, I), a groove, 0, into which an annular strip of rubber,d, is inserted.

D is the waste-pipe, and e e are the entranceapertures to theoverflow-channel, which, as

in wash-bowls of this class, is in communica tion with the waste-pipe.

It will be seen by reference to the drawings that the annular rubberstrip is considerably larger than the interior of the bowl.Consequently, when the lid is forced into the bowl, the outer edge ofthe rubber forms a close joint with the side of the bowl, and afterpassing below the top of the wash-stand, is prevented from beingwithdrawn except by introverting the rubber. ble handle.

It is designed to ornament the cover by marbleizin g the upper surfacethereof, so that when it is in place it will have the appearance ofbeing a depressed surfaced in, and a continuation of, the marble top.

I am aware that plugs for the waste-pipes of washbowls have been madewith a metallic center piece and a rubber ring, whichisinserted in agroove in the edge of the center piece, as shown in Patent No. 190,768,May 15, 1877, and that metallic covers for wash-bowls have heretoforebeen used with aflexible gasket attached to theirlower surface, to forma joint with the upper edge of the bowl; but in neither of theabove-named devices is the rubber introverted in its application to thebowl.

I therefore claim as my invention- 1. A top or cover for a stationarywash-bowl, which consists of a rigid center piece having a peripheralgroove, and an introvertible annular rubber strip of extendedsuperficial area secured in the said groove, substantially as specified.

2. In combination with the top and bowl of astationary wash-stand,having the inner edge of the former extending within the latter, so

The lid is provided with a suitaas to produce a lip or projection, asdescribed,

groove, and an introvertible annular rubber strip secured in the saidgroove, substantially as specified.
